French soldiers patrol the Terminal 2E of the Paris-Charles-de-Gaulle airport in Roissy-en-France, north of Paris, as part of France's national security alert system Vigipirate. The anti-terrorism Vigipirate plan which has been reinforced in the wake of recent attacks will be maintained in France "as long as risk prevails", French Interior minister Bernard Cazeneuve said.

The second Islamist gunman in the Charlie Hebdo magazine attack has been given a secretive burial in an unmarked grave near Paris, authorities said on Sunday, as police across Europe probed jihadist threats.
Cherif Kouachi, one of two brothers who killed 12 people in the attack on the satirical weekly on January 7, was buried just before midnight on Saturday in a cemetery in Gennevilliers, a day after his older brother Said was discreetly buried in the northeastern city of Reims.
Cherif's family, including his widow, kept away from the funeral, the mayor's office said, and the grave was left anonymous to avoid it becoming "a pilgrimage site" for Islamists.
The brothers were shot dead by police after a three-day manhunt following the slaughter at Charlie Hebdo, which had angered many Muslims around the world with its repeated publication of cartoons against the prophet.
Anger erupted in a string of majority Muslim countries after the satirical magazine responded to the massacre by running another caricature last week, showing the prophet under the headline "All is forgiven".
The worst unrest has been in Niger, where at least five people were killed and some eight churches were torched on Saturday. Around 1,000 youths wielding iron bars, clubs and axes rampaged through the capital, hurling rocks at police who responded with tear gas.
Demonstrators attending a banned political rally unconnected to the Charlie Hebdo controversy clashed with police in the capital Niamey on Sunday.
Meanwhile, a memorial rally was due in Paris on Sunday in memory of policewoman Clarissa Jean-Philippe, who was gunned down by Amedy Coulibaly, another Islamist gunman who claimed to be working with the Kouachi brothers and was also shot by police.
More arrests
French investigators were focusing on 12 people detained early on Friday and being questioned over "possible logistical support" they may have given to the Paris gunmen, sources said.
Neighbouring Belgium deployed troops on the streets for the first time in 35 years after security forces smashed a suspected Islamist "terrorist" cell planning to kill police officers.
Greek anti-terror police arrested at least four people suspected of links to the dismantled jihadist cell on Saturday.
The violence in France and Belgium and the continuing security crackdown has highlighted fears in Europe over the threat posed by residents returning home after fighting alongside Islamist groups in Syria.
Britain will hold a meeting of the coalition against the Islamic State group on Thursday, two weeks after the Paris attacks by gunmen claiming to act on behalf of the jihadist group and Al-Qaeda.
Foreign Secretary Philip Hammond and US Secretary of State John Kerry will host the one-day talks in London to discuss progress on tackling the Islamist militants.
'Do not yield'
French Foreign Minister Laurent Fabius condemned "the use of violence" in Niger while President Francois Hollande said France was committed to "freedom of expression", calling it "non-negotiable".
In a speech, Hollande urged his compatriots not to change their habits, because "to do so would be to yield to terrorism".
A survey released on Sunday however found 42% of French people thought publications should avoid running cartoons of the prophet, and 50% favoured limiting freedom of expression on the Internet and on social networks, according to the poll for the weekly Le Journal du Dimanche.
